Flag Hinge Adjustment
Flag hinges are available in many formats from different manufacturers, as flag hinges have more adjustment than butt hinges they are more popular with french doors due to the weight of the sashes causing the doors to drop. Flag hinges can be adjusted up and down as well as sideways adjustment meaning that the doors can be tilted to correct their position once a door has dropped (sagging towards the center of the door).
The grub screw that is visibe when the door sashes are open offer sideways adjustment, to correct a dropped door the top hinge should be very slightly pulled inwards, and the bottom should be wound outwards slightly. Be sure to make small adjustments and note the direction that you have would the screws.
